I just compared the two speakers today. The amp was the new Mcintosh MA252 Hybrid integrated. An older top of the line Arcam CD player (good enough) and Nordost cables.
It was a very close call. I liked both of them. The Dynaudio seemed to go a little lower but the SF seemed perhaps more punchy in the bass. The Dynaudio was more even from top to bottom and more balanced overall. But I also found it all a bit matter of fact and boring. I mean slightly in comparison. The SF had more character. A bit warmer and less sibilance. A little thicker sounding. Maybe more fun and inviting sound. I could really be happy with either one. If I had to choose it would depend on the amp. I wouldn't use solid state with the Dynaudio as I think they need some tubes somewhere in the chain or they might get sharp with voices and bad recordings compared to Dynaudios of the past. With the Mac amp I'd give a slight edge to the SF because I think I found the music a little more interesting and it held my attention more. However, I do appreciate the top to bottom evenness and the over-all coherence of the Dynaudio. Really hard choice and you can't go wrong with either one.
